Abstract
A method forming at least a portion of a cable comprises providing at least one cable conductor core, extruding at least an inner layer of a polymeric insulation material over the at least one conductor core, providing a plurality of strength members having a coating of the polymeric insulation material, heating the at least one cable conductor core and the strength members, embedding the strength members into the inner layer of the cable conductor core, and extruding an outer layer of the polymeric insulation material over the cable conductor core and the plurality of strength members and bonding the outer layer to the inner layer and the coating to form the cable and provide a contiguous bond between the inner layer, the strength members, and the outer layer, wherein the polymeric insulation material of the inner layer, the strength member coating, and the outer layer are amended to enable the inner layer and the outer layer to melt at a greater rate than the strength member coating.
